anonymize.solutions vs Strac
Both platforms detect and anonymize PII, but differ fundamentally in data residency, privacy architecture, and detection methodology.
anonymize.solutions offers 100% EU data residency on Hetzner Germany, Zero-Knowledge architecture where we never access your data, and deterministic Hybrid detection with 260+ entity types. Strac is US-based with AI-powered detection and focuses primarily on SaaS DLP with Slack/email integrations. Choose anonymize.solutions for EU compliance requirements and data sovereignty. Choose Strac for US-focused SaaS DLP with communication platform coverage.

Deterministic vs AI-based detection
The fundamental difference: how each platform identifies PII in your data, and why it matters for compliance.
Hybrid Detection (NLP + Pattern + Checksum)
Three deterministic engines working in parallel. Every detection is reproducible, auditable, and explainable.
- NLP Engine — Microsoft Presidio with spaCy, Stanza, XLM-RoBERTa
- Pattern Engine — 317 regex recognizers with checksum validation
- Checksum — Luhn (credit cards), MOD 97 (IBAN), format verification
- Result — Same input always produces same output
AI/ML-Based Detection
Machine learning models trained on data patterns. Detection quality depends on training data and model version.
- ML Models — Proprietary AI-trained detection
- Data Processing — Cloud-based inference
- Scope — Focused on SaaS DLP use cases
- Result — Model-dependent, may vary across versions
Reproducibility for compliance audits
When regulators ask why a specific field was flagged as PII, deterministic detection provides a clear, reproducible answer: which engine, which pattern, which rule. AI-based detection cannot guarantee the same output twice.
Zero-Knowledge vs standard cloud processing
The most critical architectural difference: who can access your data during and after processing.
Password Never Leaves Your Device
With anonymize.solutions, your master password is processed locally using Argon2id key derivation. The server never receives, stores, or has access to your password. Even our own team cannot decrypt your data.
AES-256-GCM Encryption
All token mappings and encrypted data use AES-256-GCM authenticated encryption. Keys are derived from your personal password via Argon2id. Without your password, data is cryptographically unrecoverable.
Zero Text Storage
Text submitted for anonymization is processed entirely in memory and immediately discarded. No original text is written to disk, logged, or retained. We log events, never data content.
Strac uses standard cloud processing: data is sent to their US-based servers for AI inference. While they implement security best practices, the fundamental model requires the provider to access your data during processing. For EU organizations subject to GDPR and Schrems II, this creates a data transfer compliance challenge.
Flexible deployment vs SaaS-only
anonymize.solutions offers three deployment models to match your security and compliance requirements. Strac operates exclusively as a SaaS platform.
anonymize.solutions Deployment Models
- Online Hosted (SaaS) — Fully managed on EU infrastructure. Fastest to deploy, zero maintenance overhead
- Managed Private — Dedicated instance on your preferred EU cloud. We manage, you control the perimeter
- Self-Managed — Run on your own infrastructure with full control. Air-gapped option available via cloak.business
Strac Deployment
- SaaS Only — Cloud-hosted on AWS (US). No self-hosted or private cloud option available
Integration Comparison
| Integration | anonymize | Strac |
|---|---|---|
| REST API | ✓ | ✓ |
| MCP Server (AI IDEs) | ✓ | ✗ |
| Office Add-in | ✓ | ✗ |
| Chrome Extension | ✓ | ✓ |
| Desktop App | ✓ | ✗ |
| Slack Integration | ✗ | ✓ |
| Email DLP | ✗ | ✓ |
Different focus areas: anonymize.solutions prioritizes document processing, AI safety, and developer tooling (MCP, Office Add-in, Desktop). Strac prioritizes SaaS DLP with communication platform integrations (Slack, email, Zendesk). Choose based on where your PII exposure risk is highest.
Switch from Strac in three steps
For API-based integrations, migration is straightforward. Map your existing calls and switch in a single day.
Evaluate with free trial
Sign up for an anonymize.solutions account and test with your actual data. Compare detection results side-by-side with your current Strac output. Verify entity coverage for your specific use cases.
Map API endpoints
Map existing Strac API calls to anonymize.solutions REST API endpoints. Both platforms use standard REST patterns — endpoint mapping is typically a 1:1 translation. Our documentation provides migration examples.
Switch — same-day migration
Update your API credentials and base URL. For API-based integrations, the switch is immediate. For workflow automations, test in parallel before cutting over. Zero downtime migration is standard.
